I only find those with the qfp chip, with the qfn it belongs and they cost too much ... I use them to test new fluxes and tin of all types, plus professional soldering techniques with top of the range wellers with all types of tips. .. A lead and lead free ... 👍🏻
It is my own design for a PCI to UART card. Which QFN chip do you have? I could make a test PCB. I can give you the Gerber files and you have to use webs like jlcpcb, pcbway... to manufacture PCBs.
@@JrSflor thanks, no I just wanted to buy the boards and the chip with many components to solder on, also the micro resistors from 0201 and the 01504 nano ones are needed ... I have to test the temperatures with hot air stations and soldering tips that come out new many of my soldering stations and many other things such as ovens and reballing machines etc ... then always with these boards and components I always use different soldering and desoldering techniques obviously I also use k thermocouples to be more precise.
@@JrSflor no thanks, I need cards including qfn chips like yours in the video that have the smallest resistors in the world and also capacitors etc. all smt smd, you understand? sorry my bad english, i'm italian and i use google translate. the cards and chips are just for testing, any model is fine, I get the complete ones from $ 5 each in AliExpress, with everything in bulk and the qfp chips, the qfn are separate and cost too much, in my laboratory they are full of electronic boards, but I also need new ones ... if you know where to buy them, you would be kind to send me some links ... surely I'm missing something ... 😉
